I'm trying to create a partition for Windows, but I'm getting the message "disk cannot be partitioned because some files cannot be moved." A poster in another thread concerning this problem said that to create a partition, Bootcamp needs continuous space or something. I do have many large files, and I had up to 3 GB free out of 180 a few minutes ago until I deleted some files to get about 58 GB. I tried partitioning with 45 GB and got the error message. I also tried lower numbers, but nothing worked. I'm assuming it's because my files are fragmented. Then I looked up defragment in the forums and found that many people are against it whether it's because it "slows down the computer" or "it is unnecessary." Now I'm in a bind because I don't want to reinstall my OS, but now I'm hearing I shouldn't defrag either. Can I get some solutions?
